Impedance is a measure of the opposition to the flow of current in an electrical circuit. It consists of two parts called resistance and reactance. Light bulbs add resistance to an electrical circuit, and reactance occurs when electricity passes through coils of a wire like those found in electric motors. Impedance Z in ohms (?) may be expressed as a complex number, where the real part represents the resistance and the imaginary part represents the reactance. Use this information to solve the problem.The circuit contains two light bulbs and two electric motors. Find total impedance to the nearest tenth of an ohm by calculating the modulus of Z.
